Abstract

The work presents the assessment of unaccounted withdrawal of fluvial anadromous and river fish species in the inland fisheries of the Astrakhan region, which is composed of despoliations of commercial catches, poaching and amateur fishing. Methodology decisions that are developed at the CaspNIRKh were the calculation basis of the unaccounted fishing withdrawal and assessment of the impact of amateur fishing on the aquatic bio-resources. The article shows the evaluation method of volumes of poaching fish withdrawal. It is found that the main objects of the unaccounted withdrawal were more valuable fishing species (roach, pike perch, catfish, carp, bream, and pike). The despoliation of commercial catches made 28% on the average. One year minimum poaching fish withdrawal in the region, using the example of 2015, was 7.94 thousands of tones and 19% from commercial catch, and 20-30% of fish catching, harvested by the amateur fishing. The work presents the pressing of unaccounted withdrawal of fluvial anadromous and river fish species on stocks. On the back of decrease of stocks and commercial catches of fluvial anadromous and river fish species, development scales of all directions of unaccounted withdrawal in the Astrakhan region disturb all preconditions for reconstruction and growth of fish number.
